I've never heard of it so I googled and looked around a bit and I think I would give your vet a call to see what they think and make sure it sounds like a safe supplement. I read the ingredients and it's unclear how any of them would stop the afflictions mentioned in the ad so I would be wary - if it sounds too good to be true, it most likely is. (Red flag - chicken fat is supposed to be good for your dog? That counters everything I've ever read about it.)
